B24047-30344000-001-410-03 Installations de gaz, d'eau et de drainage à l'intérieur des bâtiments

Such as for the scope of the contract, the works are defined as the renewal of the complete sanitary installation in the Altbau (excluding the restaurant supply), replacement of existing cast-iron radiators in WC areas with modern panel radiators including valve exchange and adapted connections, installation of an automatic make-up water unit in the basement, relocation of a heating трасse in the 5th floor, renewal of heating circuits in ventilation centres and connection to new heating coils, and rectification of various fire protection deficiencies. The place of performance is Trebbiner Str. 8–9, 10963 Berlin (Friedrichshain-Kreuzberg), on the site of the Deutsches Technikmuseum. The execution period runs roughly from 18.01.2027 to 30.06.2029, with binding intermediate contractual milestones for Bauphase I (18.01.2027–27.10.2027), Bauphase II (28.10.2027–16.08.2028) and Bauphase III (17.08.2028–04.06.2029). The Leistungsverzeichnis specifies numerous detailed positions (e.g. Baustelleneinrichtung, container provision, construction water, transport and disposal, installation and commissioning), all to be priced including ancillary services and taking account of limited on-site storage areas, transport routes (up to 100 m, stairwells 1.20 m wide, 3 m high), and noise/dust protection.

Such as concerning award criteria and weighting, the procurement is conducted under VOB/A EU with the sole stated Zuschlagskriterium “Preis”; no qualitative weighting or additional criteria are mentioned. Electronic submission of tenders via the Berlin Vergabeplattform/RIB Tender is mandatory; paper tenders are excluded. Multiple offers per bidder are allowed, but variants as such are not permitted and electronic catalogues are disallowed. The bid validity period is 60 days from the bid deadline (17.11.2026, 10:30), and electronic contract award, invoicing and payment are required. The contracting authority reserves the right, if the initial contractor fails (e.g. insolvency, termination), to award the remaining services at the originally offered prices to another bidder in descending order of economic ranking, subject to (re-)checking that bidder’s suitability.

Such as for risks and special conditions, the documents impose extensive obligations and constraints on the contractor. These include: strict adherence to the Betriebssicherheitsverordnung and accident prevention regulations, permanent on-site presence of at least one German-speaking supervisory employee, naming of a site manager and responsible coordinator, daily securing and closing of all site areas, and work-daily site safety checks. Numerous items are defined as “Nebenleistungen” included in unit prices: coordination of street use and any traffic safety measures if the bidder considers road closures necessary (all permits and costs to be calculated into prices), multiple trips, participation in site meetings, preparation of as-built drawings and documentation, performance of required tests, and adaptation/relocation of site installations without extra payment. There is a strict non-smoking and no-music rule on site, mandatory insurance proofs for all workers (absence leads to expulsion without claims), comprehensive rules on waste separation, container locking and documented disposal via weigh tickets, and mandatory weekly digital site reports. Compliance with the Berlin environmental procurement directive VwVBU and the use of appropriately certified materials (e.g. Blauer Engel or equivalent proof) is compulsory, with certificates, material data sheets and approvals to be provided immediately after award. Questions must be submitted by 09.11.2026, 12:00; a site visit is strongly recommended and can be arranged via the Baumanagerin or, during her absence, via the planner.

Such as regarding contradictions or clarifications within the documents, the texts largely reinforce each other rather than conflict. For example, the Leistungsverzeichnis states that construction water and power are provided by the client, but elsewhere a position for temporary Bauwasser installation (including permits and fees) is described; the resolution appears to be that basic supply is provided bauseits, while special temporary installations are the contractor’s responsibility and must be priced accordingly. Similarly, one passage notes that the client anticipates no special permits or road closures, but another assigns all responsibility and cost for any street-land use to the contractor if he deems such measures necessary; the applicable rule is that the contractor may not claim extra payment if his own assessment requires permits—these are part of his price. Where RIB Tender terms mention general platform availability and liability, they do not override the procurement rules; the binding provisions for bidders are those in the TED notice, the Berlin Vergabeplattform tender documents (including BerlAVG, VOB/A EU, VOB/B), and the specific project LV and answer catalogue, with the more specific procurement and project-related statements prevailing over generic platform conditions.
